If auto execution is enabled when creating an FlightStream AIM, the AIM will execute FlightStream just-in-time on Linux with the command line:

FlightStream script.txt > flightstreamOut.txt

and on Windows with the command:

FlightStream -hidden -script script.txt > flightstreamOut.txt

In both cases the FlightStream executable is assumed to in the PATH environment variable.

The analysis can be also be explicitly executed with caps_execute in the C-API or via Analysis.runAnalysis in the pyCAPS API.

Calling preAnalysis and postAnalysis is NOT allowed when auto execution is enabled.

Auto execution can also be disabled when creating an FlightStream AIM object. In this mode, caps_execute and Analysis.runAnalysis can be used to run the analysis, or FlightStream can be executed by calling preAnalysis, system, and posAnalysis as demonstrated below with a pyCAPS example:

print ("\n\preAnalysis......")
flightstream.preAnalysis()
 
print ("\n\nRunning......")
flightstream.system("FlightStream.exe -hidden -script script.txt"); # Run via system call in inputs analysis directory
 
print ("\n\postAnalysis......")
flightstream.postAnalysis()
